Definitions

  • the present invention relates generally to recovery catheters for use in vasculature. More particularly, the present invention is directed towards recovery catheters for filtering devices and systems which can be used when an interventional procedure is being performed in a stenosed or occluded region of a blood vessel to capture embolic material that may be created and released into the bloodstream during the procedure.
  • Embolic filtering devices and systems are particularly useful when performing balloon angioplasty, stenting procedures, laser angioplasty or atherectomy in critical vessels, especially in vessels where the release of embolic debris into the bloodstream can occlude the flow of oxygenated blood to the brain or other vital organs, which can cause devastating consequences to the patient.
  • the embolic protection devices and systems are useful with any vascular interventional procedure in which there is an embolic risk. Recovery catheters are essential to the successful retrieval of such protection systems and thus, to the success of the interventional procedure being performed.
  • a variety of non-surgical interventional procedures have been developed over the years for opening stenosed or occluded blood vessels in a patient caused by the build up of plaque or other substances on the wall of the blood vessel.
  • Such procedures usually involve the percutaneous introduction of the interventional device into the lumen of the artery, usually through a catheter.
  • a guiding catheter or sheath is percutaneously introduced into the cardiovascular system of a patient through the femoral artery and advanced through the vasculature until the distal end of the guiding catheter is in the common carotid artery.
  • a guide wire and a dilatation catheter having a balloon on the distal end are introduced through the guiding catheter with the guide wire sliding within the dilatation catheter.
  • the guide wire is first advanced out of the guiding catheter into the patient's carotid vasculature and is directed across the arterial lesion.
  • the dilatation catheter is subsequently advanced over the previously advanced guide wire until the dilatation balloon is properly positioned across the arterial lesion.
  • the expandable balloon is inflated to a predetermined size with a radiopaque liquid at relatively high pressures to radially compress the atherosclerotic plaque of the lesion against the inside of the artery wall and thereby dilate the lumen of the artery.
  • the balloon is then deflated to a small profile so that the dilatation catheter can be withdrawn from the patient's vasculature and the blood flow resumed through the dilated artery.
  • the above-described procedure is typical, it is not the only method used in angioplasty.
  • Atherectomy is yet another method of treating a stenosed blood vessel in which cutting blades are rotated to shave the deposited plaque from the arterial wall.
  • a vacuum catheter is usually used to capture the shaved plaque or thrombus from the blood stream during this procedure.
  • abrupt reclosure may occur or restenosis of the artery may develop over time, which may require another angioplasty procedure, a surgical bypass operation, or some other method of repairing or strengthening the area.
  • a physician can implant an intravascular prosthesis for maintaining vascular patency, commonly known as a stent, inside the artery across the lesion.
  • the stent is crimped tightly onto the balloon portion of the catheter and transported in its delivery diameter through the patient's vasculature. At the deployment site, the stent is expanded to a larger diameter, often by inflating the balloon portion of the catheter.
  • Prior art stents typically fall into two general categories of construction.
  • the first type of stent is expandable upon application of a controlled force, as described above, through the inflation of the balloon portion of a dilatation catheter which, upon inflation of the balloon or other expansion means, expands the compressed stent to a larger diameter to be left in place within the artery at the target site.
  • the second type of stent is a self-expanding stent formed from, for example, shape memory metals or super-elastic nickel-titanium (NiTi) alloys, which will automatically expand from a collapsed state when the stent is advanced out of the distal end of the delivery catheter into the body lumen.
  • NiTi super-elastic nickel-titanium
  • emboli into the circulatory system can be extremely dangerous and sometimes fatal to the patient.
  • Debris that is carried by the bloodstream to distal vessels of the brain can for example cause these cerebral vessels to occlude, resulting in a stroke, and in some cases, death. Therefore, although cerebral percutaneous transluminal angioplasty has been performed in the past, the number of procedures performed has been limited due to the justifiable fear of causing an embolic stroke should embolic debris enter the bloodstream and block vital downstream blood passages.
  • the filtering device does not have a suitable mechanism for closing the filter, there is a possibility that trapped embolic debris can backflow through the inlet opening of the filter and enter the blood-stream as the filtering system is being collapsed and removed from the patient. In such a case, the act of collapsing the filter device may actually squeeze trapped embolic material through the opening of the filter and into the bloodstream.
  • Certain of the available filters which can be expanded within a blood vessel are attached to the distal end of a guide wire or guide wire-like tubing which allows the filtering device to be placed in the patient's vasculature when the guide wire is manipulated in place. Once the guide wire is in proper position in the vasculature, the embolic filter can be deployed within the vessel to capture embolic debris. The next step then involves removing the captured debris and filter device from vasculature.
  • a retrieval catheter Since the efficient and effective retrieval of a filter which has captured vasculature debris can be highly critical to the success of an interventional procedure, the structure of a retrieval catheter must facilitate such retrieval. Accessing a filter or embolic protection device can be a concern where the interventional site is defined by tortuous or narrow anatomy. Interference between the filter and recovery catheter can also occur, where for example, the components become entangled. Identifying an exact location of the recovery catheter with respect to a filter device can also become a critical concern.
  • a recovery catheter that embodies structural characteristics specifically designed to facilitate the advancement thereof through narrow and tortuous vasculature to an interventional site. It is also desirable that a superior end portion of the recovery catheter be configured to avoid interferences with a filter device and provides an effective receptacle for the filter.
  • the present invention satisfies these and other needs.
  • the present invention is directed towards a recovery catheter for use in vasculature.
  • the recovery catheter can be employed to receive and retrieve various medical devices placed within vasculature of a patient.
